How Much Recycled Concrete Aggregate for a 14x16 Shed Base?

How much recycled concrete aggregate for a 14x16 shed base is a quick volume problem. 224 square feet at 4 inches comes to 2.77 cubic yards. Recycled concrete aggregate usually weighs about 1.2 to 1.4 tons per cubic yard, so plan on roughly 3.6 tons.

The math for a 14x16 shed base

  1. Area: 14 × 16 = 224 sq ft.
  2. Depth in feet: 4 ÷ 12 = 0.333 ft.
  3. Cubic feet: 224 × 0.333 = 74.7 cu ft.
  4. Cubic yards: ÷ 27 = 2.77 yd³.
  5. Tons: × 1.3 = 3.6 tons.

About recycled concrete aggregate

Recycled concrete aggregate is crushed old concrete. It compacts well and often costs less than virgin stone, which makes it a common driveway and pad base. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.

Preparing the shed base

Level the footprint, extend the stone a foot or so beyond the shed walls for drip and drainage, and compact in lifts. A timber or block border holds the pad shape. Since the shed base carries a shed floor frame, a little extra depth is cheap insurance.

Ordering tips

  • Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
  • Delivery size. 4.0 tons fits in a single typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
  • Bulk vs bags. At this size bulk delivery is usually the practical choice.
  • Where it drops. Have the truck dump as close to the shed base as firm ground allows.

Good and poor uses for recycled concrete aggregate

Works well for:

  • Driveway and pad bases
  • Temporary construction entrances
  • Fill under slabs when compacted in lifts

Less suited to:

  • Near ponds, streams or sensitive plants, since fresh crush can raise pH
  • Decorative top layers
  • Drainage layers, unless the product is clean and screened

Quick reference numbers

  • Per inch over 100 sq ft: about 0.40 tons of recycled concrete aggregate (0.31 cubic yards).
  • Per inch over 1,000 sq ft: about 4.0 tons.
  • Another size for comparison: a 14x28 area at 4 inches takes about 6.3 tons.
  • Weight used here: about 1.3 tons per cubic yard.

Common estimating mistakes

  • Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
  • Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
  • Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
  • Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
